EyeLine Golf Impact Cube 4 sides with 4 Impact positions The Wedge Lean side is slanted so a forward leaning Wedge matches the angle There is a 7 iron lean and a vertical Driver lean side, too There is also a round side Flip the Impact Cube on its top and you have a side (the Wedge Lean) that is slanted toward you. Set the ball "under" the slant and it is the ideal tool for teaching an inside attack angle and preventing the "over the top" move
